The TTR gene provides instructions for producing a protein called transthyretin. This protein transports vitamin A (retinol) and a hormone called thyroxine throughout the body. To transport thyroxine, four transthyretin proteins must be attached (bound) to each other to form a four-protein unit (tetramer).
Without the reserve ticket the wait for the ferry was 1.5 hrs, it took us about 20 minutes to get through the screening and board the boat. If you have noon or so tickets you can easily visit both Ellis Island and the Statue of Liberty. They also didn't seem to be real strict on the time, we were 1/2 hour early and they just sent us through.
There are 354 steps to get to the crown of the Statue of Liberty, and visitors should plan on a 30 minute climb. Those interested in visiting the crown need to make reservations through the ferry company ahead of time at statuecruises.com or by phone at 877-523-9849.
